ATI Performance Products ATI918464 Super Damper Harmonic Balancer Internal Balance

The ATI Performance Products ATI918464 Super Damper is a high-performance harmonic balancer engineered to protect your engine from destructive torsional crankshaft vibrations at all RPM levels. Unlike factory dampers and non-dampened pulleys that offer minimal protection, this Super Damper utilizes advanced elastomer construction technology to provide balanced dampening throughout the entire RPM range.

Key Features:

• Aluminum and steel construction with black hard coat finish
• 5.670-inch outside diameter with 7 percent overdriven pulley design
• Internal balance configuration with elastomer dampening system
• Six-groove serpentine belt design for OEM accessory compatibility

• SFI 18.1 certified for competition use
• Nine crankshaft pulley bolt holes with single keyway
• Includes mounting hardware for complete installation

Engineered for street use, this Super Damper maintains OEM serpentine groove locations while delivering superior vibration control. The three-ring elastomer system continuously adapts to changing engine harmonics, protecting your crankshaft, bearings, and internal components from premature wear. Exceeds SFI 18.1 Safety Certification standards, making it legal for NHRA and IHRA competition.
